Signs and Science
It was believed for a long time that Eggs can be made to stand on its end only during equinoxes. A superstitious belief rooted in the scientific fact that earths pole is tilted just the right amount so the day and nights are equal in length. Science has destroyed that belief and down goes one fond tradition of people in China; placing eggs on its end during equinoxes.
One Wayne Osborn, in Central Michigan University, has a tabulation of eggs standing on its end. The experiments ran for 3 whole months including the autumnal equinox on the 22nd of September.
All this because one equinox just passed us on March 22. This is supposed to be the official start of Spring! As Jon said: It bitter cold out here. If you see a ground hog, make sure to punch him in the face.
